PROCEDURE OF SPINDLE SERVICE

PROCEDURE OF REPAIRING A SPINDLE

The effort of a Spindle depends directly on the performance of the reconditioning. Profit by our longtime experience in spindle repairs and reconditioning, which are done by means of definite activity and a established quality assurance system. Irrespective of the application and the type of spindle, we respond fast and competently to all requests around the spindle.

Gladly we will carry out the mounting and de-mounting of your spindle in your ground. Our engineer tests all feed lines, converters and cooling units for their reliability.

Below a short workflow of a standard spindle repair:

1. RECEIVING INSPECTION

After the consignment, the spindle is registered optically and technically by a standard repair protocol. If it‘s possible, the spindle is checked in order to discover further damage or errors, which can only be discovered when the spindle is mounted.

2. DE-MOUNTING AND ESTIMATE OF COSTS

The spindle is completely de-mounted in order to discover the failure cause and the actual state of the components. The most important parts are cleaned and calibrated. The failing parts are documented

(if it‘s possible with a photo).

The estimate of costs for the repair is drawn up on the basis of the determined data and discovered damage. Moreover, we will advise you on the technical questions and, if it seems sensible and economical, we will make a proposal to optimise your spindle for the production process. 

3. QUOTATION RELEASE

We send you a detailed offer für the approval of costs.

The repair is only being continued after a previous consultation and approval on your part.

4. ACQUISITION AND OVERHAUL

Parallel to the cleaning of all components, the replacement parts are commissioned or bought. As well occurs the overhaul of the used parts and of their functional surface, such as shaft, bearing shield, tensioning system or seal seats. If it is impossible to overhaul a part we will reproduce it.

5. FINE-BALANCING

All rotating parts of a spindle are balanced after DIN-ISO 1940. This method is the condition so that the repaired spindle works with low vibration values.

6. MOUNTING

The mounting of the single tested components is done by each engineer  on highest concentration and direct responsibility.

7. GREASE DISTRIBUTION RUN / RUN-IN PROCESS

Afterwards, every spindle is subjected a grease distribution run or run-in process. This assures that the spindle is in a ready-to-operate state without running-in.

After finishing the run-in process the spindle is being finest-balanced and gains its final balancing quality.

8. TEST RUN AND QUALITY ASSURANCE

Finally, every spindle is submitted a test run. All parameters, e.g. the temperature, the vibration, the rotation, drawing force, switching status, rotary encoder etc. is approved. All values relevant for the spindle are documented in a test protocol and enclosed when the spindle is delivered. Each spindle is led with an individual personal life-time-record.
